I started a little catering business on the side. Italian and French cooking is a passion of mine, and I had this plan of starting a catering business. While it is a fun side project, I came to the conclusion that I wouldn't want to do it fulltime. I can live with the pay cut if you're doing something that you love, but after a while you kind of miss using your brain instead of your hands. The upside is that you're directly in contact with your customers, which is refreshing after building web apps for people you never meet in person. Very rewarding to see and hear that they are happy with something you've made.
Occasionally I do a catering gig, so it's more like a nice, paid hobby.
On a side note, if you're looking for a stress-free job, don't do anything that has to do with restaurants or catering. It's like juggling six flaming torches in one hand while being yelled at.
